Are 2 + 6x and 2(3x + 1) equivalent
Solnce55 [7]

✳︎ ✳︎ ✳︎ ✳︎ ✳︎ ✳︎ Hello There! :)

To determine whether the two expressions are equivalent, we take the second expression and distribute 2:

2(3x+1)

6x+2=2+6x

And now we know the two expressions are equivalent. If you look, you will remember the Commutative Property that states:

a+b=b+a

In this case, a=6x and b=2.

So we know that the two expressions are equivalent.

Hope this helps! :)

Choose the symbol that correctly compares the fractions below.<br> 8/9 ? 1/9
gladu [14]

Answer:

Which means that this equation is also true: 8/9 > 1/9

Step-by-step explanation:

Is 8/9 less than 1/9? Is 8/9 smaller than 1/9? These are the same questions with one answer.

To get the answer, we first convert each fraction into decimal numbers. We do this by dividing the numerator by the denominator for each fraction as illustrated below:

8/9 = 0.889

1/9 = 0.111

Then, we compare the two decimal numbers to get the answer.

0.889 is not less than 0.111.

Therefore, 8/9 is not less than 1/9 and the answer to the question "Is 8/9 less than 1/9?" is no.

Christina is building a slide for her kids. The ladder is 4 feet tall and the slide is 9 feet long. What is the distance between
xxMikexx [17]

Answer: 8.1ft

Step-by-step explanation:

It may help to draw it out but for this question you would have to use pythagoras' theorem.

The formula for the shorter side is a²=c²-b²

The height of this triangle is 4ft (b) and the hypotenuse (the diagonal that stretches from the top to the bottom) is 9ft (c).

When we put the numbers in the formula you get a²=9²-4²

9²=81

4²=16

a²=81-16

a²=65

Then because we want to find a on it's own you would have to square root 65 which is 8.1 (to the nearest tenth)
